Improvements in Acetylene-Gas Machines, of

which the following is a specification.

My invention relates to means to control the feed of carbid in suchmachines and to other features thereof hereinafterdescribed; and theobject thereof is to provide a simple and efiicient machine. Iaccomplish this object by the mechanism described herein and illustratedin the accompanying drawings, in which Figure 1 is'a cross-section takenon line 1 1 of the generator andgas-holder. Fig. 3 is a side elevation,partly'in section, with parts broken away. Fig. 4 is a central verticalsection of the carbid-chamber and its outletchamber with thecarbid-controlling valves in'elevation. Fig. 5 is a detail of the top ofthe valve-operating rod. 2

In the drawings, 6 is the carbid-chamber, which is provided with a port7.in the .bottom thereof, which opens into chamberS, which I will call asafety-chamber. This safetychamber is provided with a port 9 in thebottom thereof, which opens into a hood 10, that opens into thegenerator-chamber 11, projecting downwardly thereinto. On thelower endof the casing of the safety-chamber is a moisfrom running down theoutside wall of the safety-chamber to the outlet thereof. The topof thecarbid-chamber is provided with a screw-cap 13, which is removed when itis desired to refill the chamber.

ports a cap 15 secured thereto, which cap A brace 14 sup- .covers theupper end of the carbid-valve-oper- :ating rod 16, upon which isslidably mounted a sleeve 17, which carries near its lower endconical.-shaped valves" 18 and 1.9, which control port 7 ofthecarbid-chamber and port 9 ;of the safety-chamber. v the carbid as itfalls from the safety-chamber Valve 19 willdeflect -so it will fall intothe water at a point outside of the vertical line projected from themoisture-collar 12, thereby causing the principal part of the steam toarise outside of the collar. Below valve 19 is asupporting-cone 20,

. .which is rigidly secured to the valve-operating rod 16. Thisvalve-operating rod carries on the top thereof, within cap 15, a nut 21,be-, tween which and brace 14 is spring 22, which is adapted normally tohold valve 18 so that it closes port 7 and valve 19 to close port 9.This rod is U-shaped, as best shown in Fig. 2, and passes upwardly and.out of the generating-chamber through the guide-tube 23, which issecured in partition 24, which partition forms the top of thegenerating-chamber.

A sealing-tube 25 is secured to rod 16 and istelescopically movable upontube 23 to prevent any gas escaping upwardly through said tube. Theexterior end of rod 16 terminates in a yoke16, and between this yokeand'cover 26 is spiral spring 27, which also normally .holds valves 18and 19 to close ports 7 and 9, respectively. Mounted on the top ofgas-bell 28 is a standard 29, which carries an arm 29,

which passes through yoke 16' and is adapted tocontact therewith anddepress the valveoperating rod so as to open valves 18 and 19 when thegas in saidbell is nearly exhausted. Should an excess of carbid fallinto the generator-chamber by reason of the failure of valves 18 and '19shutting ofit' the supply of carbid, the accumulation of gas in the bellwill cause it to rise until arm 29 contacts with the top of the yoke andwill raise said rod to a height sufficient to seat valves 18 I and 19 orwillprevent the further rise of the gas-bell, at which time ports 30 insealing -tube 31 will be so close to the waterline 32 in the gas-bellthat the gas will pass through said ports 33 in sealing-tube 34, whichis telescopically movable upon pipe 35, which pipe opens into thecondensing-chamber 36 and serves as an escape-pipe for the gas whichpasses therethrough and into the condensingchamber and from thencethrough pipe 37 and.

through outlet 38, (shown in Fig. 1,) which outlet may be connected bypipe to lead the gas outside the building if the gas-machine is keptwithin an inclosed building. The generator-chamber is provided with afillingspout 39, and the water necessary to fill the machine passestherefrom through port 40 and thence through tube 41, having a number ofsmall ports 42 in the vertical wall thereof and near its bottom, asshown in Fig.2. This tube I will call a filling-tube, and passingtherethrough is rod 43,. having handle 44 on the top thereof andstirrer-blade 45 on the I bottom thereof, which stirrer is operated tocause the ash to flow out through pipe 46 when the machine is beingcleaned. Leading from the generator-chamber is the supply- 5 pipe 47,which terminates in the gas-bell. On the pipe 47 is a three-way valve48, which valve is also connected to pipe 37 This valve 51 leads the gastherefrom to the place of use.

' The safety-chamber is removably secured to the top of chamber by bolts54. Hood 1O 1 is provided with a plurality of holes 55,through which thegas that rises in the hood is forced in detached streams, therebywashing the gas better than if it were not separated into jets.

Arm 29 is slidable through its support 29, which support is secured tothe gas-bell, so that when it is desired to refill the machine said armcan be removed away from engagement with yoke 16, thereby permittingsprings 22 and 27 to bring valves 18 and 19 to close ports 7 and 9,respectively, when the chambercan be refilled.

It will be observed that in case the user neglects to disconnect arm 29from yoke 16 Valve 19 will be in the position shown in Fig. 4:, whichcloses port 9, and that the safetychamber will fill with carbid and thatthe valve will not rise so as to open port 9, and the carbid will thenhave to be removed from the machine and valve 18 permitted to close port7 before the carbid-chamber is in a proper position to receive a newsupply, thus putting an effective check upon the improper filling of themachine, as no carbid can possibly get into the water in the generatoruntil the valves are in their proper position. As soon as thecarbid-chamber is refilled and cap 13 replaced the carbid-operating rodis depressed by hand until the gas-bell rises to a point where arm 29can be slid back with the end thereof projecting through yoke 16. Itwill also be observed that as ports 42 are in the vertical wall of thefilling-tube and that the tube is in close engagement at the bottom withthe stirreroperating rod no gas will escape therethrough and that saidtube performs the functions of a seal around this stirrer-rod and afillingtube. The condensing-chamber 36 is provided with a filling-spout52 for filling said chamber with the necessary water, which passesthrough port 53 into said chamber.
